ManU shouldn't spent most of their money on a striker. Berbatov, Tevez and Rooney are all world class. What they need is a great offensive midfielder that can get them the ball. David Silva, Ribery would be ideal and should be affordable with Ronaldo's transfer fee + a little extra. They probably also need a new goalkeeper with Van der Sar retiring soon. Rene Adler would probably the best pick who's also available at a decent price.
